不逐字复制聊天记录。
problem_object、submitter_name、submitter_org 必须能在当前资料中找到依据。
environment 未明确出现时保持空字符串，不要自行填写生产环境。
tags 只提取资料中明确出现的产品、模块、错误码或故障类型关键词，无法确定时返回空数组。

7. related_system 优先使用事实值；知识库只能在高度匹配且不引入客户实体时辅助判断。
8. 缺少业务必填字段时将字段名加入 missing_fields，并按重要程度生成最多 5 个简洁追问。
priority 使用默认值 medium 时不列为缺失。
9. field_evidence 必须逐字段返回置信度、材料引用、最短原文、定位和冲突；无证据时
使用 0、空数组和空字符串。人工确认字段的 source_refs 使用 manual_field。
10. message_timeline 只整理资料中真实出现的消息；说话人、角色或时间不确定时保持空值、
role 使用 unknown、降低 confidence 并写入 conflict，不得编造时间。occurred_at 保存带时区
